| description | The invention discloses a high-airspeed high-activity heavy naphtha desulfurizing agent and a preparation method thereof. The high-airspeed high-activity heavy naphtha desulfurizing agent consists of the following components: 30-50% of activated aluminum oxide, 5-20% of a molecular sieve, 20-40% of a first active metal element, 10-30% of a second active metal element and 1-5% of an auxiliary agent, the method comprises the following steps: 1, uniformly mixing an oxide containing active metal elements with a carrier raw material to obtain dry powder; 2, preparing the dried powder into pellets to obtain a desulfurizer A; 3, carrying out equivalent-volume impregnation on the desulfurizer A by using a mixed salt solution containing active metal elements to obtain a desulfurizer B; 4, activating; and 5, carrying out surface oxidation treatment. The carrier, the active substance and the auxiliary agent are designed, so that the adsorption capacity and the sulfur capacity of the desulfurizing agent are improved; by |
